Smart Plotter Program - Design an application that displays a menu to ask the user to choose whether to: (20 marks) (a) Plot the relationship between the temperature and time using bar chart using the following instructions − Load a file that contain an array of 10 days − Load a file that contain an array of 10 corresponding sales amounts at which the sales were done. − Determine the total sales and print the output. (b) Plot on the same graph for the functions f(x) = x + 3, g(x) = X2 +1, f(x)*g(x) and f(x)/g(x) for the range x values from -1 to 1. (c) Quit the Smart Plotter The user can choose then proceed to plot a simple 2D line, a scatter plot or bar chart. The program will continue displaying the menu to allow the user to choose until the user chooses to quit the application

Try this code:

function smart_plotter()
    while true
        disp("---- Smart Plotter Menu ----")
        disp("1. Plot Temperature vs Sales")
        disp("2. Plot Functions")
        disp("3. Quit")
        
        choice = input("Enter your choice (1-3): ");
        
        switch choice
            case 1
                plot_temperature_sales();
            case 2
                plot_functions();
            case 3
                disp("Exiting Smart Plotter...");
                break;
            otherwise
                disp("Invalid choice. Please try again.");
        end
    end
end
function plot_temperature_sales()
    try
        temperature_file = input("Enter the file name for temperature data: ", 's');
        sales_file = input("Enter the file name for sales data: ", 's');
        temperature = load(temperature_file);
        sales = load(sales_file);
        bar(temperature, sales);
        xlabel("Temperature");
        ylabel("Sales");
        title("Temperature vs Sales");
        total_sales = sum(sales);
        disp("Total sales: " + total_sales);
        pause;  % Pauses execution until the user closes the plot window
    catch e
        disp("Error: " + e.message);
    end
end
function plot_functions()
    x = linspace(-1, 1, 100);
    f = x + 3;
    g = x.^2 + 1;
    fg = f .* g;
    fg_div = f ./ g;
    plot(x, f, 'DisplayName', 'f(x) = x + 3');
    hold on;
    plot(x, g, 'DisplayName', 'g(x) = x^2 + 1');
    plot(x, fg, 'DisplayName', 'f(x) * g(x)');
    plot(x, fg_div, 'DisplayName', 'f(x) / g(x)');
    hold off;
    xlabel("x");
    ylabel("y");
    title("Function Plots");
    legend('Location', 'best');
    pause;  % Pauses execution until the user closes the plot window
end
smart_plotter();
